Title: Heat exchanger for air conditioner using internally grooved tube and manufacture thereof
Inventor: SHINOHARA YOSHIHIRO
IPC: F28F9/26
Filed: 1987-05-26
Abstract: PURPOSE:To restrict the consumption amount of a brazing material as much as possible, which would be increased by the presence of internal surface grooves, and also to prevent a crack from developing to the internal surface grooves during the bellmouth-like expansion of a grooved tube, by forcibly giving plastic deformation to the internal surface grooves and crushing them before mounting a return bend tube in the grooved tube after the internal surface grooves have been formed on the portion to be brazed. CONSTITUTION:The outside diameter Dm of a mandrel 2 is made to coincide with the outside diameter Do of an internally grooved tube 1, the minimum inside diameter Di thereof and the inside diameter of said tube 1 in a state that the ridge 1a of the internally grooved tube 1 has been crushed and a groove portion 1b thereof has been filled up. After the internally grooved tube 1 having a straight tube shape cut into a length suitable for final use has been placed in and secured by a press die 3, the mandrel 2 having the outside diameter Dm is pushed thereinto. In this instance, the internally grooved tube 1 is secured by the press die 3, and the inside diameter thereof becomes Dm because the ridge 1a is crushed, but the outside diameter of the tube remains unchanged. In such a manner, the internally grooved tube 1 whose predetermined portion is smoothened is thereafter to be treated by a method of the bellmouth-like expansion of the tube.

Abstract: PURPOSE:To stabilize and promote a mixing action, to stabilize flame holding, to reduce the generation of noise, and to shorten a flame, by a method wherein a main flame on a combustion cylinder is formed in the shape of a fish tail. CONSTITUTION:A plurality of air holes 3, 4, and 5 are provided in a combustion cylinder 2, and the air holes are arranged in a dense manner at the upper part and are aligned in a coarse manner at a lower part. Especially, for example, a horizontal projection part 6 is formed on an upper peripheral wall surface, and a slitlike air holes 3 is formed in the projection part 6. The slitlike air holes 3 may consist of a plurality of pores, which serve such that an air flow injected therethrough forms a radial flow around the combustion cylinder 2 acting as a central axis or a swirl flow. This causes the shape of an air flow to spread in a radial manner to form the shape of a fish tail, and the mutual air flows are superposed with each other in a flower-leaf manner, and at the forward ends of the fish tail shapes, an air curtain is formed by all of them. This enables to perform combustion with sharply reduced noise and permits a decrease in the size of a total combustion chamber.

IPC: B22F3/02
Filed: 1981-08-21
Abstract: PURPOSE:To form molded parts of uniform density by exerting uniform external pressure thereupon from axial and right angle directions with soft rubber as a pressure medium. CONSTITUTION:Axial load is exerted upon the powder 5 packed in a vessel 6 having a small modulus of elasticity and large deformability by means of a pressurizing rod 8. An elastic material 9 such as rubber is disposed between the vessel 6 and the rod 8. Therefore, the soft rubber layer 10 on the wall of an outside frame 7 is pressurized in a right angle direction by the material 9 in parallel with the regular loading in the axial direction. As a result, the layer 10 spreads in the right angle direction and the loads in the axial and right angle direction is exerted uniformly upon the powder 5. Here, a sealing ring 11 and an auxiliary sealing ring 12 are formed of rigid rubber and prevent the phenomena wherein the layer 10 flows plastically from between the rod 13 and the frame 7 on account of an increase in pressure.
